We've experimented with that at SVT (Sweden's public service broadcaster). Or rather, the video team has, I'm just a web dev, so I don't know the details other than what's in this blog post:
That's the thing - when the plant is outside it will get sun from multiple directions as the sun moves, but when it inside the light will only be coming from the window.
And even outside the sun is shining more from one direction (south here in the northern hemisphere), since it is below the horizon at times, which will often cause plants and trees to have more branches and leaves facing that direction.
It feels like they're also prime candidates for making a tour with them as actual robots (or holograms), so they wouldn't even need to tour themselves.
I recently found this video of Billy Gibbons performing in the street in Helsinki without anyone noticing. I like that he becomes less recognizable when not wearing sunglasses.
It's touring again. At least outside of the US. I was at the one in Stockholm, Sweden two years ago. It was supposed to come back last year, but you know...
There is a Swedish podcast (Snedtänkt) that has a lovely email address for contacting the show (I've translated from Swedish) - preferablyonlypositiveresponse@[email provider].
Not sure if it actually works, but I think it might prime people into a more positive mindset.
On a similar note I loved that emails from Readmill came from pleasereply@readmill.com as a contrast to the usual user hostile noreply addresses most companies use.
Reminds me of The pattern on the stone by W Daniel Hillis where he builds a tic-tac-toe computer out of mechanical components. It's a great book for explaining how computers actually work.
